Transferring Garuda Linux Installation with Corrected GRUB and Initrd

Transferring a Linux installation from one machine to another, especially when dealing with boot issues like incorrect GRUB or initrd configurations, requires careful steps. Here's how you can achieve this without needing the original install disk.

Understanding the Problem

When you clone an existing Garuda Linux installation using dd, it copies everything exactly as is, including the bootloader (GRUB) and initial ramdisk (initrd). These components are configured for the hardware of the first machine. When moved to a different computer, they may not work correctly due to differences in disk layout or hardware configurations.

Steps to Correct GRUB and Initrd

1. Prepare the Target System

Boot into a live environment on the target system using any Linux distribution that can run from a USB drive.
Ensure you have root access, as modifying boot settings requires administrative privileges.

2. Identify Disk Partitions

Use lsblk or fdisk -l to identify the partitions on your target machine. Note down the device names (e.g., /dev/sda, /dev/nvme0n1) as you'll need them for mounting and configuring GRUB.

3. Mount the Filesystem

Mount the root partition of your Garuda Linux installation: bash sudo mount /dev/sdXn /mnt Replace /dev/sdXn with the appropriate device name and partition number.
If you have separate boot or EFI partitions, mount them as well: bash sudo mount /dev/sdYn /mnt/boot # For a separate boot partition sudo mount /dev/sdZn /mnt/boot/efi # For an EFI system partition

4. Chroot into the Installed System

Bind necessary directories and chroot: bash for dir in /dev /proc /run /sys; do sudo mount --bind $dir /mnt$dir; done sudo chroot /mnt

5. Update GRUB Configuration

Install grub if it's not already installed: bash pacman -Sy grub efibootmgr os-prober
Generate a new GRUB configuration file: bash grub-mkconfig -o /boot/grub/grub.cfg

6. Install GRUB to the Correct Disk

Install GRUB to the target disk (replace /dev/sdX with your actual device): bash grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=Garuda --recheck /dev/sdX
For BIOS systems, use: bash grub-install --target=i386-pc /dev/sdX

7. Update Initrd

Regenerate the initramfs for all installed kernels: bash mkinitcpio -P

8. Exit Chroot and Unmount Partitions

Exit chroot environment: bash exit
Unmount all mounted directories: bash for dir in /sys /proc /run /dev; do sudo umount /mnt$dir; done sudo umount /mnt/boot/efi # If applicable sudo umount /mnt/boot # If applicable sudo umount /mnt

Final Steps

Reboot the System: Once everything is set up, reboot your system and remove any live USB drives.
Check Boot Configuration: Ensure that GRUB loads correctly and allows you to boot into Garuda Linux.

By following these steps, you should be able to transfer your Garuda Linux installation to a new machine with a properly configured bootloader. If issues persist, consider checking hardware compatibility or consulting the Arch Wiki for more detailed troubleshooting related to GRUB and initrd configurations.
